Answer:
Explanation:
The distance from Dallas to Houston is 362,000 meters:
Tom drives with an average speed of:
Then, knowing these values, you can use the following formula in order to find the time "t":
Therefore, substituting values into the formula, you get:
Rounded to the the hundredths place:
To solve this problem it is necessary to apply the concepts related to energy as a function of voltage, load and force, and the definition of Force given by Newton in his second law.
By definition we know that force is equal to
F= ma
Where,
m = mass (at this case of an electron)
a = Acceleration
But we also know that the Energy of an electric object is given by two similar definitions.
Where,
F= Force
q = Charge of proton/electron
V = Voltage
d = Distance
Equating and rearrange for F,
The two concepts of force can be related to each other, then
Acceleration would be,
Replacing with our values we have that the acceleration is
Now through the cinematic equations of motion we know that,
Where,
Final velocity
Initial velocity
a = Acceleration
x = Displacement
Re-arrange to find v_f,
Therefore the electron's speed when it is 0.1 cm from the negative plate is
Answer:
0.79 cm
Explanation:
The computation is shown below:-
Particle acceleration is
We will take d which indicates distance as from the negative plate, so the travel by proton is 0.800 cm - d at the same time
After solving the equation we will get 0.79 cm from the negative plate.
Therefore it is 0.79 cm far from the negative pate i.e the point at which the electron and proton pass each other
